[Scene: Shabbat afternoon, post-lunch. Donny and I are struggling not to fall asleep directly on our cholent.]
Me: Guys, if you let Mommy and Daddy sleep when Nadav goes in for his nap, I'll pay you four shekel. Each.
Yaakov: Five shekel.
Donny: Four shekel if you play nicely together, one shekel if you also clean up after.
Me: "Playing nicely" means no fighting, no screaming and don't wake us up unless a limb is missing or there is a copious amount of blood spurting from somewhere.
Yaakov and Ariella: Okay.
We shake hands all around.
I sleep for two hours.
Best 10 shekel I ever spent.
